I want to analyze the kinds of topics that appear in SQA questions. Questions are tagged, and you can determine how many questions are associated with each tag. I would like to know, for example, how many questions are in the union of selenium and selenium2, or going further, which test-automation questions are neither selenium nor selenium2. Is there a tool for that?
There aren't that many questions on SQA. I know I could write something to grab the data question-by-question from the site, but I would rather not.
